Lucas Martell's podcast is a companion to the launch of his short animated film, Pigeon Impossible. Each episode is entertaining in its own way (check out episode 2, "Writing is Rewriting") and most of them focus on the animation process, but episode 12 speaks directly to the festival circuit. In particular listen to Martell's advice about output formats and why the extra expense of converting your short to 35mm film might give you a leg up on the competition. Now that's what I call a film festival secret.
